This paper presents a robust mixed force and displacement control strategy for testing of base isolation bearings in real-time hybrid simulation. The mixed-mode control is a critical experimental technique to impose accurate loading conditions on the base isolation bearings. The proposed mixed-mode control strategy consists of loop-shaping and proportional-integral-differential controllers. Following experimental validation, the mixed-mode control was demonstrated through a series of real-time hybrid simulation. The experimental results showed that the developed mixed-mode control enables accurate control of dynamic vertical force on the base isolation bearings during real-time hybrid simulation. 相似文献

ABSTRACTAboriginal and Torres Strait Islander people navigate the social and political order of the Australian settler state in ways that seek to increase their personal freedoms and political autonomy. For some groups this means seeking a firmer place within the social, political and economic life of Australia, and for others it means navigating away, towards a more distant relationship based in the resurgence of Indigenous nationhood. This navigation is composed of multifaceted and multidirectional relations between Indigenous Australians, settler Australians, and the settler state. As a discipline, political science must move beyond the study of settler institutions and begin to engage more comprehensively in research that considers the dynamics and structures of Indigenous-settler relations as a matter of priority. 相似文献
